Anyone who has ever played Arkham Horror knows that it takes up a huge amount of room. The board is huge, there are tons of tokens, everyone has a character sheet, and to top it all off, there are a full 21 different decks of cards. Here is an example of JUST the cards used in the game:

Those familiar with the game may notice that with the Ancient One standing vertical like this, you can't use doom tokens to fill up their doom track anymore. Instead, I use the blue brick full of holes along the front of the holder to keep track.

When I finally manage to get some of the expansions I will obviously need to modify this, but it works great for now.
